Hello deadhog,

I know Black & Decker uses this brush on quite a number of their products. And they are attached differently depending on the model of product that you have. If you could post the model number of the product in question , we should be able to help you with your question.

I also have a brush problem...
I've taken most of the rtx 3s rotary tool apart, but can't find diagrahms or info on
how to get to and replace brushes. I hope they are the same as the dremel...they
are the only ones I could buy.
